One of the key irritants for many motorists is passengers who loudly slam doors on boarding / disembarking. Drivers of minibuses and taxi drivers especially do not like such “poppers” – and they often stick unambiguous warning stickers on the glass.
And negligent lovers to knock the door harder at best can expect an irritated look or statement, and at worst it comes to assault.
Why are they so indignant, and is it really dangerous? In fact, such claps are not terrible for a new and completely serviceable car. But on cars with high mileage, problems can arise.
During their long life, such cars drive through a huge number of bumps and holes. The blows received from them are reflected not only on the parts of the chassis, but also on the body, skin and internal mechanisms.
These include, for example, door locks made up of many different metal parts. They gradually loosen up, ceasing to hold strong loads. And sometimes an extra strong bang of the door can be, as they say, the last straw. The lock settings get confused, it stops snapping normally or does not snap at all. Then the normal opening and closing of the door becomes a problem.
Not only the mechanical part of the lock can fail, but also the limit switch, which gives a signal to close the door. Then an icon on the dashboard may light up, signaling the open doors, and in some cars also an annoying sound signal. Both are unpleasant.
In addition to locks, other problems can appear on older vehicles. Rubber bumpers and seals can come off the mounts – with strong cotton, it is on them that the main blow goes. Also, the fastenings of the plastic sheathing can loosen, which is why then “crickets” appear in the cabin – unpleasant rattling sounds. And on cars that have survived not very high-quality body repairs, a door slammed from the heart can cause cracks in the putty.
The suction cup of the mobile phone holder, which has fallen off as a result of slamming the door, can also cause particular irritation to the driver. In old cars, where the ventilation system is already clogged up and normal air exchange is disrupted, a short-term increase in air pressure arises from a strong and abrupt closing of the door.
This can lead to pawing of the ears of everyone who is in the cabin, and on especially older cars, such pressure can even provoke further growth of cracks on the windshield, or even partially squeeze it out. So don’t slam doors, especially in old cars.
